Versuchsvorschrift

To a solution of 4 g (14.7 mmol) of 4,5-diacetamido-1-chloro-2-nitrobenzene in 200 ml of ethanol were added a solution of 0.4 g of copper(II) sulfate×5H2O in 2 ml of water and subsequently, a little at a time, 1.1 g (29.4 mmol) of sodium borohydride. The mixture was refluxed for 3 hours and subsequently filtered. The filtrate was concentrated, and the crude product was washed with water and methylene chloride. Workup of the organic phase gave a yield of 94% of the product.
